Physical weathering is caused by physical processes such as changes in temperature, freezing and thawing, and the effects of wind, rain and waves.
hope this helped
As we know that,
1 mm Hg = 1 torr
So,
745 mm Hg = X
X = (745 mm Hg × 1 torr) ÷ 1 mm Hg
X = 745 torr
Also,
1 mm Hg = 133.325 Pa
So,
745 mm Hg = X
X = (745 mm Hg × 133.325 Pa) ÷ 1 mm Hg
X = 99327 Pa
Result:
Option-A (745 torr) is the correct answer.
Answer:
B. During the light reactions of photosynthesis, water is split, removing electrons and protons, and oxygen gas is released.
Explanation:
In Photosynthesis two phases occurs. They are grouped into light dependent and light independent phase (dark phase) reactions. In the light dependent phase, sunlight is trapped by chlorophyll and water is split into its components ( oxygen, hydrogen ions and free electrons; photolysis). Part of the electrons and the hydrogen ions are picked up by NADP (Nicotinamide adenine dinucleotide phosphate) converting it to NADPH and part of the electrons are used to replenished the photosystems trapping the sunlight.
